Bill O'Reilly says he has no qualms about sharing the stage with a
comedian when he debates Jon Stewart at a charity fundraiser Saturday
in Washington, D.C.

"I lot of people think I am a
comedian," O'Reilly says. "I don't worry about perceptions. ... Either
you like me or you don't. Either you get what I do or you don't."

The
90-minute debate, "The Rumble in the Air-Conditioned Auditorium" at
George Washington University, matches the stars of Fox News and Comedy
Central. They have been guests on each other's shows several times.

O'Reilly
says there's no doubt whom the "left-wing media" will declare the
winner, "no matter what happens. Jon Stewart doesn't even have to show
up."

"I know that," he says. "What I'm going in for is a few
laughs. I"m going to have my facts. I always do. I'm going to confound
Stewart with the facts. He'll confound me with his 16 writers."

Stewart,
who often mocks Fox News on his "faux news" show, responds: "Oh, my
God, it's only been one sentence and he's already got his facts wrong."

O'Reilly
says he's not concerned about blurring lines between entertainment and
journalism: "I don't worry about blurring anything. I'm a commentator.
That's what I am. Commentators can comment in a variety of forums. Do I
worry that Barack Obama is not the president because he goes on The View? No."
